Hepatotoxicity induced by acute and chronic paracetamol overdose in adults. Where do we stand?
Paracetamol (Acetaminophen) poisoning data can reveal the potential deficiencies of paracetamol poisoning management guidelines. We conducted a retrospective cohort study of patients >18years who were attended in the emergency department (ED) of a Spanish tertiary hospital, from 2005 to 2010 for suspected paracetamol overdose and who had measurable paracetamol concentrations. 208 patients suspected of paracetamol poisoning were identified. The annual incidence in the ED increased from 2.0 (95%-CI: 0.2-7.2) cases per 10,000 patients in 2005 to 3.4 (95%-CI: 1.1-8.8) in 2010. ⋯ We conclude that the incidence of suspected cases of paracetamol poisoning at our hospital is increasing. The majority of toxicity cases, including ALF, associated with the ingestion of paracetamol were due to chronic poisoning. This finding constitutes an important warning regarding paracetamol chronic poisoning, and clinicians should have a higher index of clinical suspicion for this entity.

Hydrocodone bitartrate is the most commonly used drug for acute and chronic pain in the U. S. with over 135 million prescriptions in 2012. The U. ⋯ The FDA has rescheduled hydrocodone from Schedule III to Schedule II which went into effect on October 6, 2014, along with a limit on added acetaminophen of 325 mg for each dose of hydrocodone. This review examines the evolution of hydrocodone into a common and yet controversial drug in the U. S. with its pharmacokinetics, pharmacodynamics, safety and efficacy.

Randomized Controlled Trial
Tramadol versus codeine/acetaminophen after pediatric tonsillectomy: A prospective, double-blinded, randomized controlled trial.
Tonsillectomy is one of the most common pediatric surgical procedures performed in the United States. The postoperative period can be particularly painful, and there is currently no consensus on an optimal analgesic regimen. The objective of this study was to evaluate efficacy and safety of the single drug tramadol versus codeine/acetaminophen post-tonsillectomy. ⋯ As part of multimodal analgesia, scheduled plus as-needed tramadol may be considered for children in the postoperative setting due to its analgesic properties, low potential for side effects, and good safety profile.

Painful diabetic neuropathy is difficult to treat. Single analgesics often have insufficient efficacy and poor tolerability. Combination therapy may therefore be of particular benefit, because it might provide optimal analgesia with fewer adverse effects. ⋯ In the tail-flick test, isobolographic analysis revealed 15-, and 19-fold reduction of doses of both drugs in the combination of levetiracetam with aspirin/ibuprofen, and paracetamol, respectively. In the von Frey test, approximately 7- and 9-fold reduction of doses of both drugs was detected in levetiracetam-ibuprofen and levetiracetam-aspirin/levetiracetam-paracetamol combinations, respectively. These results show synergism between levetiracetam and ibuprofen/aspirin/paracetamol in a model of painful diabetic neuropathy and might provide a useful approach to the treatment of patients suffering from painful diabetic neuropathy.

Drugs with potential chemopreventive properties in relation to epithelial ovarian cancer--a nationwide case-control study.
Ovarian cancer has a poor prognosis because the disease in the majority of patients is diagnosed at an advanced stage as a result of nonspecific symptoms and lack of efficient screening methods. Because of the poor prognosis of ovarian cancer and the challenge of early detection of the disease, identification of protective factors is important. It has been suggested that some commonly used drugs may have a protective effect against cancer, including ovarian cancer; however, the literature on chemopreventive measures for ovarian cancer is sparse and the results are inconclusive. ⋯ Additional research, ideally from clinical trials, is needed before our observations may lead to recommendations for chemopreventive measures against ovarian cancer. In case consensus points to a true protective effect of paracetamol or low-dose aspirin, comprehensive risk-benefit evaluations will also have to be performed. We hope that our results will encourage researchers to look more deeply into the potential chemo-preventive effects of the study drugs against epithelial ovarian cancer risk.
